Dual Axis with Phase Control

Test oversized products using Dual Axis with Phase Control by synchronizing two shakers moving in the same direction.

Dual Axis Applications

SINE

Enter two values out of the four between Acceleration, Frequency, Velocity, or Displacement, and the calculator will do the rest.

RANDOM

Run Controlled spectrum random tests (tests with a spectrally shaped Gaussian amplitude distribution).

SHOCK

Run standard classical shock pulses as well as (optional) user-defined or SRS synthesized transient pulses.

SHOCK RESPONSE SPECTRUM (SRS)

Perform a Shock Response Spectrum (SRS) analysis. Run a shock pulse defined by a frequency vs. G peak table.

Dual Loop control is achieved by using the two outputs from one VR9500/VR10500 I/O unit. The drive output and the aux (COLA) output are both used to drive different shakers. The same profile drives both shakers.

Sine: Same profile; adjustable phase angle between the two outputs, +/- 360 degrees
Random: Matched phase between the two outputs, auto controlled
Transient/Shock: Matched phase between the two outputs, auto controlled
